I was in Vybor with the Gunter 2, equipped the M4. At 10:30 am, an automatic server restart should have occurred, and I was removed from the game.
When I entered the server again, I was standing on the roof of the Gunter. I continued my journey, the next stop I noticed that my M4 had disappeared. Neither in the vehicle inventory, nor in their own Invetar can be found!
